QUENTIN W. BOOTH, OF ROCHESTER, NEW YORK.

TURNING- MACHINE.

SPECIFICATION forming' part of Letters Patent No. 534,420, datedFebruary 19, 1895.

Application filed April 15, 1893. Serial No. 470,480. (No model.)

To all whom it may concern:

Be it known that I, QUENTIN W. BoorH, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Turning-Machines, of which the following is aspecification. l

The present invention consists in improvelments upon the class ofbeading machines which is represented in Letters Patent No. 495,776,granted to me April'lS, 1893. AThese improvements consist of improvedmeansfor imparting the compound movement to the irons or blades, of animproved pivotal connection for the irons or blades, and of improvedmeans for adjusting the relative positions of the operating ends of theirons or blades.

The invention is illustrated in the accompanying drawings, wherein-Figure 1, is a front view and Fig. 2, a side view partly broken away,illustrating the improvements. Fig. 3, is a detail view of a modi- `iiedmeans for adjusting the relative positions the machine is to turn,stretch and spread theA scallops of the button-nies of ladies shoes.

A is a support, standard or base, on which all the other parts aremounted.

B, O, are two turning irons or blades each of which has a combinedvertical and lateralv movement in the plane of its blade, the rela` tivearrangement and operation of the two irons or blades being such thattheir working edges move to and from each other in similar curves; andwhen acting upon the scallops of button-nies or upon analogous seams theirons or blades operate as a spreader for spreading or stretching Ythesame.

The drive-shaft. H, provided wlth a drivepulley a extends parallelwith'the plane and paths of the irons B and C, instead of at rightanglesthereto, which is of advantage both in rendering the machine morecompact, and in enabling the vdrive belt to be connected to the 'pulleya without crossing or with fewer guide' pulleys. Motion is communicatedfrom the shaft H to the irons by a single cam-block I, which is carriedby and rotates with the shaft and which is located between the feet ofthe two irons B, O. Thek cam-block has two cam faces m n (see Fig. l) onits periphery for imparting to the respective irons'vertical or1ongitudinal movements, and cam faces o p on its sides for imparting thelateral movements to the respective irons. The feet of the irons B, C,have toes j respectively, which co-operate with the cam-faces m nrespectively, and have also adjustable h eels la Z which co-operate withthe cam-faceso p respectively. The adjustable heelsare composed ofscrews which enable them to be laterally adjustable both to take up wearand to vary the relative positions (and hence the extent of movement) oflthe operating or head ends of the irons. The heels kl are maintained incontact with the cam faces o p by an extension spring J, which isconnected at opposite ends to the irons B, C, respectively. The toes t jare maintained /in contact with the cam faces m n by compressson springsK which are interposed between the pivot blocks L andthe bottoms ofslots c in the ironsB, C. Each iron is slid- .ingly pivoted on apivot-block'L, and has a rectangular slot e which embraces the block Land allows thelongitudinal movement of the iron. Each pivot-block turnsindependently on a stud M fastened Yto the support A.

This stud maybe madeV vertically adjustable by slottin-g the standard A,as in my said Patent No. 495,776. A guard-plate N (see Fig.

2,-it is omitted in l) covers the slots and y ling a longitudinalmovement and a lateral movement, in combination with a rotating camhaving a peripheral cam face which gives the IOO longitudinal movementand a cam face on its side which gives the lateral movement,substantially as set forth.

2. In a turning machine two turning irons each havinga lateral and alongitudinal movement, in combination with a shaft, and a cam thereon,said cam having peripheral cam faces which give the longitudinalmovements and side cam faces which give the lateral movements,substantially as set forth.

3. In a turning machine the turning iron having an adjustable heel,substantially as set forth.

4. In a turning machine the turning iron having an adjustable rotatableheel with faces at different distances from the center of rotation,substantially as set forth.

5. In a turning machine the cam, and the two irons having adjustableheels, in combination with the spring between the two irons formaintaining their adjustable heels in con tact with the side cam facesof said cam, substantially as set forth.

6. In a turning machine a pivot, and an iron having a slot embracingsaid pivot, in combination with a cam, and a spring between said pivotand the bottom of said slot for maintaining said iron in (3o-operationwith said cam, substantially as set forth.

7. In a turning machine, a turning pivotblock having parallel sides, incombination with an iron having a slot with parallel sides embracingsaid pivot-block, and means for QUENTIN W'. BOOTH.
